CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 458,541, dated August25, 1891.

Application filed April 2, 1891. Serial No. 387,354. (llo model.)

To whom it may concern:

Be it known that we, JEROME J. WEBsTEE, a citizen of the United States,and a resident of Somerville, Middlesex county, Massachusetts, andKIRKLEY HYDE, a citizen of the United States, and a resident of Lowell,Middlesex county, Massachusetts, have invented certain new and usefulImprovements in Cash Registers and Indicators; and we do hereby Iodeclare that the following is a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in cash registers and indicatorsof the class having tablet-rods operated through the medium ofkey-levers and sustained in the raised or exposed position by a lockingwing or rod.

The object of the invention is to dispense with intermediate trippingconnections between the keys and the locking device as well as topromptly release and bring a previ ouslyexposed tablet back to normalposition out of view when a new key begins to raise a new tablet-rod.

The invention consists, essentially, in the combination of atablet-rod-locking device and a series of operating keys or levers, theadjacent sides of these parts having inclined or cam surfaces to movesaid locking device aside-during the first part of the movement of thelevers.

It also consists in other combinations hereinafter described andclaimed.

In the drawings forming a part of this specification, Figure 1 is aperspective showing the supporting-frame and operative parts of anindicator embracing one form of our invention. Fig. 2 is a section infront of a raised key. Fig. 3 is a view with the front plate removed,showing the parts of the ap paratus partly in section and partly inelevation, one key being raised to the full extent, as in Figs. 1 and 2.Fig. 4 is a similar view, one key being partially raised. Fig. 5 is arear elevation of the frame and operative parts, the locking-frame beingshown in full lines in place to lock the tablet-rods in the raisedposition, as shown in Fig. 3, and in dottedlines in place to releasesaid tabletrods, as shown in Fig. et. Figs. 6, 7, and 8 are viewssimilar to the foregoing,showing a second form of locking-frame.

The frame-work for supporting the operating parts is contained in anyusual or appropriate case or cabinet.

Aisaframeofordinaryconstructioninwhich the operative parts are mounted;B, the keylevers; O, the fulcrum-rod; D, the tablet-rods; E, a movablelocking device or frame, and F pendants upon which the locking-frame ishung. The key-levers B are provided with downward projections b at ornear their rear ends, and each projection is provided with a notch 1, aninclined or beveled face 2, and a beveled toe part The tablet-rods andtablets (Z are of usual construction in this class of machines. Thetablet-rod teeth at, however, have by preference plane under surfaces toprovide a broad step or rest upon their supports. The supporting devicein the form of the invention herein shown consists of a frame whosehorizontal bars or rails are marked E and side pieces (2 c. The upperrail of this frame is provided with teeth 5, which serve to sustain thetablet-rods in their raised position, and the lower rail is providedwith a series of projections having double-cam faces 6 and 7,corresponding in number with that of the keys. This frame is attached tothe lower end of pendants F F by pivotal connections 8 8, and thependants are pivotally connected with the rear end of the main frame atff. By this arrangement free lateral movement of the locking-frame isprovided, so as to be easily operated through the medium of thekey-levers. The lower end of the pendants have a slight outwardandinward movement from and toward the main frame to provide for thereturn of the keys from the raised to the normal position. This isprovided for by making the pendants slightly flexible by jointing themnear the upper ends or by having the pivotal supports ff loose. A secondform of locking-frame is shown in Figs. 6, 7, and 8, wherein the frameis loosely hung from a shaft adapted to slide laterally of and swingoutward from the main frame. The lockframe is held to its normal orlooking position by spring G, and is moved laterally to drop a raisedtablet and to permit a new tablet to be raised above the lockteeth bymeans of the incline 2 on the key projection b operating against thebevel or cam faces 6 on the lower rail of the lock-frame. Theprojections I) hold the lock-frame so that its teeth 5 are out of thepath of the teeth l of the tabletrods while the rods are raised by thekey-levers; but when they have passed beyond the projections 6 thespring brings the frame back to normal position and locks thetablet-rods in the raised position, as shown in Fig. 8 of the drawings.Upon the return movement of the keys the bevel 3 strikes the cam-face 7and swings the lock-frame outward slightly, and passes down until saidpart '7 comes opposite the notch 1 in the projection b, when it isbrought back to position shown in Fig. 2 by the spring G.

The operation is as follows: hen a key is depressed, for example, 8, thetablet is raised, and simultaneously therewith the lockingframe is movedlaterally by the incline 2 Working against the cam 6. The teeth 5 of thelock-frame are thus caused to pass from under the teeth 4 of any of thetablets which may have been raised and permits such tablet to drop tonormal position. As the key continues its movement, the vertical side orface of projection 11 holds the lock-frame to one side of normalposition until the key has carried the teeth 4: of the tablet-rod abovethe lock-rod teeth 5, when the lower end of projection 1) passes abovethe cams 6 and 7 and allows the lock-frame to be returned to normalposition by the spring G. Upon the return of the key the bevel 8 engagesthe cam 7 and swings and holds the lock-frame backward until the notch 1comes opposite the cams 6 and 7, when the spring G draws the lock-frameforward to normal position.

Having now described our invention, what we claim is- 1. In acash-register, the combination of a series of operating keys or levers,a series of tablets, and a tablet-locking device for holding the tabletin view after the keys have returned to normal position, the lock andkeys having adjacent projections for moving the lock aside uponoperatinga key, substantially as described.

2. In a cash-indicator, the combination of a series of tablets, atrblet-lock for holding the tablets in a raised position after the keysare released, and a series of operating-levers, each of the levers andthe lock being provided with a projection adjoining that of the other,whereby the lock is moved aside upon operating a key, substantially asdescribed.

3. In a cash-indicator, the combination of a tablet-rod provided withteeth, a supporting rod or frame provided with teeth engaging saidtablet-teeth, and a series of keys or levers, each provided with aprojection for moving aside the supporting-frame and releasing theexposed tablet, substantially as described.

4. In a cash-indicator, the combination of a tablet-rod-locking framefor engaging the tablets, pendent supports for said frame, and a seriesof keys or levers having projections for laterally swinging the frameaside to release the tablet rod, substantially as described.

5. In a cash-indicator, the combination. of a series of tablet-rods andtablets, a lockingframe for said rods, pendent supports for said frame,and a series of keys or levers, each having a projection provided with acam-face for swinging the frame aside at the beginning of the stroke, aside face for holding it out of locking position during most of itsmovement, and a notch for permitting said frame to return to lockingposition, substantially as described.

6. In a cash-indicator, the combination of a tablet-rod-locking frameand a series of keys provided with a projection having a camface, aplane face, a notch, and a bevel or camface at or near its outerextremity for swinging and holding the frame aside, permitting it toreturn, and for throwing the frame outward to permit the return of thekey to place, substantially as described.

In testimony whereof we affix our signatures in the presence of twowitnesses.
